So I am trying to use a gate to output redstone signals to start my engines to pull items out of my machines like compressors and what not. I have found this to be ineffective with the rotary macerator and induction furnace however because if you detect if there is something in the inventory then if there is anything in the battery slot or the secondary slot for these machines it detects that there is something in inventory and starts the engines. Now the problem is the pipe doesn't draw from those slots, and I have to fill those slots so that overflow of items doesn't go into those slots, because they do for whatever reason even though im only piping input from the top. So does anyone have any ideas how to get this to work properly? Or maybe a way that pipes won't pipe into the bottom and secondary input slots of the macerator and furnace?
